TO WHOM IT MAY CONCERN: v

Be it known that we, GOTTLIEB KOEN IG and GEORGE OTTo, of Plymouth, in the county of Wayn d State of Michigan, have invented a n'ew and useful Improvement in Potato-Diggers, and we-do declare that the following is a true and accurate description thereof, referencebeing had to the accompanying drawings, and to the letters of reference marked thereon, and making a. part of this specification.

Figure 1 is a side view of our invention. I

FigureZ is a top view of the same.

The same letters indicate similar parts in each figure. I

Our object, in this invention, is to construct anapparatus' that, while it is designed to do its work. well and with speed, will be cheap in price, and brought within the means of all. r

We are aware that there are many inventions designed to aid the grower in harvesting his potatoes, but the expense attending their construction is so great that but very fewfarmer's'can aiford to purchasethem In the construction of our machine, we use two traction-wheels, A A, to which are attached the gear-wheels B B, which mesh into the piuions O O, which are hung upon the shaft D. The tractiomwheels .A A. are hung upon the crank-axle-E. Upon the shaft D are placedthe revolving teeth F F F F F, which are driven by the gear wheels and pinionsiheretofore described. G G, &c.', are a rack suspended, by the-arms H H, tothezshaft D. Through the openings between the bars of this rack the teeth .F F, &c., pass, The rear end of this rack rests upon the rollerI. J isthe seat for the driver and operator, near which -is'the lever K, by which the operator f throws the machine into or out of geaiyas he may desire. When in operation, the catch L and spring M hold the lever K in place. The revolving teeth'should bediainond-pointed, as shown in thedrawing. The red lines in fig. 1 are intended to show the position of the gearing when thrown out of use.

What we claim as our invention, and desire to secure by Letters Patent, is

The com bination of the traction-wheels AA, the gear-wheels B B, the pinions CO, the shaft D, theerankaxle E, the revolving teeth F F F F F, the rack G, the arms H H, the roller 1, the seat J, the lever K, the catch L, the spring M, with a suitable frame, when arranged substantially as and for the purpose described.
